Perform the requested operation or operations. f(x) = 4x + 6, g(x) = 5x2 Find (f + g)(x).

OpenStudy (anonymous):

first off, you'll need to distribute the "x" in equation: (f + g)(x) then use substitution, which I can show you once you're that far ^_^

OpenStudy (anonymous):

so f(x) + g(x) ? @DemolisionWolf

OpenStudy (anonymous):

bingo! now substitute in what f(x) stands for and what g(x) stands for into that f(x) + g(x) equation you got

OpenStudy (anonymous):

would that be (4x+6)+(5x^2) ?

OpenStudy (anonymous):

@DemolisionWolf

OpenStudy (anonymous):

right again! now the parenthsies can go away becuase the only thing separating them is a "+" so this: (4x+6)+(5x^2) becomes 4x+6+5x^2 can you do the rest?

OpenStudy (anonymous):

5x^2+4x+6? @DemolisionWolf

OpenStudy (anonymous):

bingo! now as far as I can tell, you just needed to do the operations, not solve for x. or do you have to solve for x?

OpenStudy (anonymous):

all it says is order of operations, thank you!

OpenStudy (anonymous):

^_^ good work!
